Abstract: A plastic package assembly method suitable for ferroelectric-based integrated circuits includes a strict thermal budget that reduces the time at temperature for four key processing steps: die attach cures, die coat cures, molding cures, and marking cures. The plastic package assembly method uses low temperature mold and die coat materials, as well as low temperature curable inks or laser marking in order to minimize degradation of electrical performance, thus improving yields and reliability. The assembly method uses a snap cure die attach step, a die coat followed by a room temperature cure, and formation of the plastic package with room temperature curable molding compounds not requiring a post mold cure. Front and back marking of the plastic package is accomplished using either an infrared or ultraviolet curable ink followed by minimum cure time at elevated temperature, or by using laser marking.

Abstract: A yield enhancement technique for integrated circuit processing which reduces the deleterious effects of H2O contamination which is absorbed by conventional dielectric films resulting in an undesired subsequent out-diffusion of hydrogen when the integrated circuit die is subsequently subjected to relatively high processing temperatures such as those experienced in CERDIP packaging. The technique disclosed comprises the formation of an interlevel dielectric layer having hydrophilic properties (for example, 7.5% phosphorus doped TEOS) at least partially surrounding a device on the integrated circuit which layer is then subjected to an annealing operation to drive off at least a portion of any moisture present therein.

Abstract: A test method for ferroelectric memories includes the steps of: functionally testing the ferroelectric memories to determine functional yield; storing the ferroelectric memories for at least eight hours; writing an initial pattern into the ferroelectric memories; baking the ferroelectric memories; reading the initial pattern to determine same state yield; writing an inverse pattern into the ferroelectric memories; reading the inverse pattern to determine opposite state yield; and again writing the initial pattern into the ferroelectric memories. The steps of baking, reading the initial pattern and writing the inverse pattern, and reading the inverse pattern and writing the initial pattern are repeated for a number of test cycles. The ferroelectric memories are baked at a temperature of about 150.degree. C. for a predetermined duration that is incremented with each successive test cycle.

Abstract: Ferroelectric capacitors in an integrated memory are renewed to improve retention performance. The renewal method is performed on a wafer containing ferroelectric memory die. In one method, a rejuvenation anneal is performed after all electrical tests, including those at elevated temperatures, have been accomplished, but before the failed die have been inked. The rejuvenation anneal is performed at or above the Curie temperature of the ferroelectric material. In the preferred embodiment, the ferroelectric material is PZT, and the rejuvenation anneal is a thermal treatment at 400.degree. Centigrade in a nitrogen flow of roughly ten liters per minute for about an hour. In another method, separate electrical cycling and depoling operations are performed to provide the equivalent benefits of the single rejuvenation anneal. The electrical cycling operation is accomplished by writing about one hundred cycles at five volts alternating logic states into each ferroelectric capacitor into the array.
